FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 325,755, dated September 1885.

Application led February 6, 1885.

.To all whom it may concern:

`Be it known that I, RUFUs S. MERRILL, of Boston, in the State of Massachusetts, have invented a certain new and useful Improvement in Folding Boxes, of which the following is a specification. 1 A

My invention has relation to a folding box or package in which the body of the box is adapted to fold fiat upon itself, and is combined with hinged or folding flaps for closing *the ends of the box.

My improvement has reference tothe end flaps, my object being to provide simple and convenient means whereby they shall be pre vented from entering or from being pushed into the ends of the box, and shall also be made to stiffen and to hold in shape the unfolded box-body. To this end I provide the body of the box with a wrapper, and I provide each end flap with a tongue on its outer or free end, the arrangement being such that when the flap is folded so as to close the end of the box its tongue will enter a pocket between between the box and the wrapper, which are so attached to one another as to form said pocket at the proper point. The result of this is that the flap cannot bepushed into the box, and the latter is stiffened and strengthened.

In the accompanying drawings, Figure l is a perspective view of a portion of a folding box enibodyingmy invention, the end liap being unfolded. A portion of the wrapper is broken away to show the iiap more clearly. Fig. 2 is a longitudinal section of the box and w rapper with the end folded and closed.

(No model.)

The body of the box is rectangular, and its four sides, A, fold up into fiat form in the usual way. It is provided at each end with a Hap, B, which forms a prolongation of one .to of' the sides of the box. It also has a wrap# per, C, which projects at the ends so that it may be folded down over the ilaps. Each Hap has at its outer or free1 end a tongue, D, p which at the point Where it joins the iiap is of the width of the latter. It slightly" tapers t0- ward its outer end, so as to facilitate its insertion into the pocket intended forit. This pocket is formed for it at the point a between the wrapper and the box, the two being so at- 5o tached together as to leave the pocket at the point specified.

In the act of closing the flap the tongue is tucked down into its pocket and occupies the position shown in Fig. 2. In this position it acts in conjunction with the wrapper to ma` tcrially stien the box, and it effectually prevents the Hap from being pushed into the box.

What I claim, `and desire to secure by Letters Patent, is*

A folding box or package, in which the sides A and a wrapper, B, connected together so as to provide a pocket, a, are combined with the end Hap, B, provided with a tongue, D, to

enter said pocket when the flap is closed,.as l

and for the purposes hereinbefore set forth.

In testimony whereofI have hereunto set my hand this 26th January, A. D. 1885.

RUFUS S. MERRILL.
